Dear Ralf & family, thank you so much for your words.
In justification to your suggestions, you were the first guests claiming about the mattress so we couldn´t improve before. Everything is new at the house and it is not easy to please all people in this matter but we will take into account your suggestion, for sure. We already fixed the fridge problem that was making some noise. The fridge is also new so the technician solved the problem easily, unfortunately we hadn´t noticed before you arrive.
About the dogs, I know that it´s not the first time that happen but it´s a punctual situation. They don´t live in our property or even in the adjacent houses. They may bark if another dog, cat or person walk near the backyard door of their house in the middle of the night to give a sign. I believe that if this were a permanent situation the neighbors would have already taken an attitude against the owners of the dogs. But once again, please accept our apologies and we will keep an eye on what is happening around.
All the best <3
